According to CoinMeta, the Shenzhen Stock Exchange and Shenzhen Securities Information Co., Ltd. have decided to revise the compilation scheme of the GEM index, gradually adjusting the upper limit of the weight of a single sample stock to 15%. The adjustment method is as follows: during each regular adjustment period, if the actual weight of the largest sample stock approaches 14.5% before the adjustment, its actual weight will be increased by 0.5% and then rounded up to become the new upper limit for that sample stock's weight after the adjustment. During the adjustment period, the weight limit and the weight adjustment factor will only be reduced, never increased, until the actual weight of the largest sample stock does not exceed 14.5%, thereby achieving the goal of a 15% weight limit. This revision will take effect during the regular adjustment on December 14, 2026.
